Dear all,
mail-filter/opendkim - committed ebuild needs one extra fix
One last design issue that I ran into during the migration.
The slotted lua ebuilds install the headers into subdirectories like
/usr/include/lua5.2, but otherwise with their upstream names. The
libraries, on the other hand, all get installed directly to $libdir..
but with NON-standard names like liblua5.2.a (as opposed to simply
liblua.a).
This makes it impossible to build against a specific version of Lua
without using pkg-config. The usual way would be to add
/usr/include/lua5.2 to the compiler's include path, and $libdir/lua5.2
to its library path (via -I and -L)... but there's no way to tell the
build system to look for a library of an entirely different name. Things
like AC_SEARCH_LIBS are going to try -llua, and that's it.
